Definitions

  • the invention relates to a method for filling water in a program-controlled washing machine with an in a tub arranged laundry tub, one Level switch, a filling valve and a control unit for a rinse cycle during which the washing drum is rotating and which connects to a wash cycle in which the Laundry was moistened.
  • the amount of free Fleet i.e. the amount of water not bound in the laundry, should usually be larger for rinse cycles than for Washes.
  • the object of the invention is a method of the beginning Specify the type mentioned by the tax simple way to fill the water in rinses adapted to the respective laundry is improved.
  • the above object is characterized by the features of characterizing part of claim 1 solved.
  • Filling valve is not closed and preferably too the rotation of the washing drum is not interrupted, but water continues to flow as the drum rotates let in during a filling time (Filling phase), which - determined by the control unit - with a long pre-filling phase longer than with a short one Pre-filling phase.
  • the filling phase is preferred proportional to the pre-fill phase.
  • the filling valve is closed, whereby the laundry drum can continue to rotate. It will a water level that is higher for rinse cycles than in wash cycles and the respective pumping speed of the Items to be washed in the rinse cycle are adjusted.
  • Level switch or a level switch with one for the Additional switching level necessary for rinse cycle There is no additional one for the described method Level switch or a level switch with one for the Additional switching level necessary for rinse cycle.
  • the water level in the rinse cycle is from the same level or level switch determined that for the level in previous Wash cycles is provided. This represents one technical simplification for the washing machine.
  • the filling process described comprises two phases. He is one stage, however, because between the two phases Filling valve is not switched on and off. Furthermore the filling process runs during the rinsing movement of the Washing drum. Both have the consequence that the Control unit, which is usually a program drum has, can be easily set up because less Program steps as required in the prior art are. Also in connection with the program drum standing microprocessor can be of a simple type be.
  • the figure shows filling diagrams of a rinse cycle.
  • a washing machine has one in a tub rotating drum. Water is in the Solution container can be admitted through a filling valve. At the A level switch is provided on the tub a target level Ns responds. Wash liquor is by means of a Pump can be pumped out of the tub.
  • the functions the washing machine - especially water intake, heating, Drum movements, draining - are done by one Control unit, for example a hybrid control unit with program drum and microprocessor, controlled. Essential parts of the program are washing, rinsing, Fling. Such washing machines are state of the art.
  • the wash liquor is suctioned off. If necessary, it is thrown in between.
  • the laundry is moist and the water level in the tub (free fleet) is low or goes to zero. In any case, it is below the target level Ns.
  • a rinse cycle should now follow.
  • the control unit rotates the laundry drum and opens the filling valve so that when turning Washing drum fresh water flows into the tub and the laundry moved by the laundry drum water up to the limit of its absorbency.
  • the control unit measures the time period tv from the beginning the wash cycle until the target level Ns is reached passes.
  • the target level Ns is not one for the rinse cycle necessary water level, but to one for the previous ones Measure the necessary water level for wash cycles and thus lower than desired for a rinse cycle.
  • the Desired level Ns is preferably such that at one Wash cycle with the smallest water level required Sufficiently large amount of not bound in the laundry Water is available. This is usually in the cooking program or the case in colored laundry programs.
  • the filling valve remains during a filling phase (Filling time tz) opened further.
  • Their duration is of the Control unit, specifically its microprocessor, determined in proportion to the duration of each Pre-filling phase.
  • Curve 1 shows a case in which the duration tv1 Pre-fill time is comparatively short, the target level Ns is achieved comparatively quickly because that is already in the previous wash cycle only dampened laundry absorbs comparatively little water. Accordingly the control unit provides a comparatively short duration tz1 for the filling time.
  • the Filling valve closed. It is then the water level N1 in reached the tub.
  • This water level N1 includes one of the loading type of the Drum and component dependent on the type of laundry. He is about the fill time stored in the control unit tz1 set so that it for the rinse this Items to be washed are sufficiently high, but for reasons of Water saving is not unnecessarily high.
  • the filling valve runs the laundry drum in the Continue rinse cycle, at the end of which a pump down he follows.
  • Curve 2 shows a case in which a longer one Pre-fill time tv2 from opening the fill valve to Reaching the target level Ns is measured. This longer one The pre-fill time tv2 arises because that comes from the previous wash cycle dampened current laundry more Water soaks up as the laundry leading to curve 1. As a result, the control unit sets a fill time tz2 which is longer than the filling time tz1. At the Switching off the filling valve is therefore a water level N2 reached, which is higher than the water level N1. This is expedient because for the rinse cycle on the laundry load, which is more until the target level Ns is reached Water absorbs as the laundry load according to curve 1, one larger amount of free water is advantageous.
  • Influencing the filling time tz as a function of the pre-fill time tv is also different Water network pressures and / or water inflow quantities per Unit of time in their influence on the respective Water level N1 or N2 off. Because if water inflows more slowly, for example, the target level becomes Ns reached later, so that the filling time tz from the Control unit is easily extended accordingly, so that despite the slow water inflow again the water level N1 or N2 is reached.
  • control unit If there is a requirement that in successive Rinse cycles - with the same load of laundry - with different water levels N1 or N2 worked this can be stored in the control unit.
  • the control unit then provides, for example, each next rinse a gradually longer filling time tz on when in successive rinse cycles increased water level is desired.
  • the filling time tz can also be taken by other measures to be influenced. For example, is the Operating option "intensive rinsing" on the washing machine provided, then can be controlled by the user the filling time tz are extended, whereupon the Rinse cycle a higher water level than N1 or N2 sets.
  • control unit can respond to a corresponding signal extend the filling time tz accordingly.
